New phone and new SIM Card got activated on the wrong number
I was activating my brother's new phone (Samsung Galaxy S20+) with the new sim card that accompanied the phone. When I used att.com/activates to activate the phone, it activated using my mother's number even though I entered my brother's number into the prompt boxes. Now, my mother's line on her iPhone is no longer reachable. I've been trying to call ATT Support for help but given the circumstances around COVID-19, I understand why the support is not so reachable lately. How do we fix this ASAP?
